5 Description:    /sys/kernel/iommu_groups/ contains a number of sub-
6                 directories, each representing an IOMMU group.  The
7                 name of the sub-directory matches the iommu_group_id()
8                 for the group, which is an integer value.  Within each
9                 subdirectory is another directory named "devices" with
10                 links to the sysfs devices contained in this group.
11                 The group directory also optionally contains a "name"
12                 file if the IOMMU driver has chosen to register a more
13                 common name for the group.
